This invention relates to a concrete torni, especially designed formolding reinforce@L concrete tence posts and tne like.

The general object of the invention is to provide a form which is strongand rigid, which will not warp from moisture or continued use, and whichmay be easily assembled or disassembled by anyone in a very short time,whereby it is possible to produce posts oi" a uniformly high quality ata minimum cost- Novel means are provided i'or securing the dii'l'erentparts oi the form in assembled relation, and for securing thereinforcing rods and the various devices for attaching wire to theposts. rlhe same mold with suitable removable parts and attachments maybe optionally used tor molding common posts 'for the major portion ofthe ience, double-size brace posts to be used near the corners or endsot the tence, and specially constructed corner or end posts.

The invention consists 'further in various details of construction andnovel arrangements, which will be more lparticularly described inconnection with the accompanying drawings illustrating the invention.

In the drawings:

ing the means for clamping and stretching the reinforcing rods.

Figure 10 is a vertical section taken on the line 10-10 of Figure 7.

Figure 11 is a detailsection showing a inodiiied torni of partition formolding posts with rounded corners.

1n carrying out the invention, a suitable platform 1 is provided, whichniay be made from matched boards or ship-lap and cov-` ered with a sheetof asphalt rooling 2, or other suitable material which is impervious tomoisture. Gn this platform are laid the sides 8 of the moldandintermediate partitions l, rEhe opposed faces of these sides andpartitions are provided at the top and bottom with cleats 5 and 6respectively, and

are then covered with sheet iron coverings 7 and 8. The ends ot the formare closed by channelshaped steel plates 9 and 10 respectively, and theends of the sides and partitions lare covered by end caps 11, formedwith channels or recesses 12 for receiving cleats 13, which are securedto the steel end plates and serve to tix the sides and partitions of themold in position. As shown in Figures 1, 5 and t3, these cleats 13 areso arranged that thev partitions con` verge toward the upper end, thusforming posts which taper from the bottom to the top.

rIhe end plates 9 and 10 are secured and held in assembled relation bymeans of hooks 14.-, which are engaged with holes in the ends of theplates, and are connected with the adjacent portions of the sidesl bystrongvcoil springs 15. After the sides, partitions and end plates ofthe mold have been assembled, reinforcing rods 16 are placed in positionbefore the concrete is poured. Each of these reinforcing rods isapproximately in the shape oi? a hairpin with the intermediate bentportieri 17 located at the upper end of the post, @ne of these hair-pinshaped rods is provided for each common post, and two for each doublepost. The plate' 9 is pressed inwardly, as shown at' 1S, where the topot each post comes, and is formed with a slot` 19 for' receiving thebent portion 17l ofthe reinforcing rod.- fter the bent portion ot therod. hasv been inserted. in the slot, a nail-I 20, or similar means, maybe passed through the saine, as shown in Figures d and The edges of theslot 19 are preferably turned under to form lips 2l, thus making iteasier to insert or remove the nail.

rllhe rod tightener coniprises a ol-shaped men'iber 22, theextren'iities ol which are curved downwardly, as seen at Q8 in Figure 9,and are adapted to bear against the outer face of the end plate 10. Thelegs of the member 22 are connected by a transverse pin 24, on which ispivoted a deg 25 having a slot 26 adapted to receive the end orn thereinforcing rod 16. The latter is adapted to project through a hole inthe plat l0 and through the slot 2G in the dog, and the dog ispreferably made of hardened steel, and the side of the slot Q6sharpen-cd so as to firmly engage the rod. The slot 26 may be tapered soas to tit rods of different si it will be understood that a tightening'member is provided for each oi the proinc ends of each rod i6.

Before the concrete has set in the mold, a ninnber oi trainierte rods 28are inserted, as shown in Figure d, to be later v'ithdiawn so as toprovide bolt holes. It will understood that each post is provided withas many bolt holes as there are strands or" wire to be attached to thepost. The rod 28 has a lug 29 secured thereto so as to provide anarcuate recess in the face ot the post, in order that the bolt whichsecures the fence wire may draw the later int-o the recess, and by itstrictional engagement therewith hold the wire more securely. he outerend of the rod 2S is provided with a handle 30, so that it may bewithdrawn from Ythe post when the latter has become suiriciently set.

The invention as shown in Figures l to 5 inclusive, is used tor makingcommon posts 3l, which are octagonal in cross section. rlhe plates 9 andl0 project somewhat above the posts, and the side pieces 3 also haveextensions 32 secured thereto, so as to prevent spilling of' theconcrete while it is being tamped into the mold. In the embodimentillustrated, provision is made :for making tive common posts at onetime, or by arranging the mold as shown in Figure 6, two double size orbrace posts 33 may be made at the same time. in making the brace posts,the first and last partitions are lett out, and the center mold is leftempty, as shown in Figure 6.

.For making a corner or end post 34, as shown in Figures 7 and lO, anextension is connected to the lower end of the mold used in Figure 6.rThis extension comprises o1- posed side walls 35 connected by bracebars 26, and having` at their lower ends oilsetportions 3? :For formingan anchor portion 3S for the post. rlfhe upper ends of the side pieces35 are inserted in the corresponding recesses or channels l2 formed atthe lower ends the sides 3 and partitions l respectively, and the lowerents of the oii set portions 37 of the side pieces 35 are secured in asupplemental end plate 39, which is provided with holes ilor receivinglugs l() formed on the lower ends et the side pieces. rllhe plate 39 isheld on the lower ends ol" the side pieces by hooks M and springs l5, inthe same manner as the end plates 9 and lO are held. F or reinforcingthe corr r posts, rods lo are used which are longer than the rods 16, tocorrespond with the length or' the post.

rihe form may be provided with interchangeable pieces and partitions otdiffert shape to mold posts ci any shape des.,- cd. YFor e aple, l haveshown in Figure ll a partition l-l, having cleats with con cave faces,and covered with sheet iron coverings l-l to form posts with roundedcorners. It is also apparent that the mold may be used for molding suchother articlesl as are desired,

it is to be particularlyT noted that th form may be very quicklyassembled, inerely by laying the side pieces and partitions on theplatform and hooking the end plates in place. As the reinforcing rodsare jflaced in position, the tightening member 2f?, may be quicklyattached to draw the rods up tightly, and this also aids in holding theend plates tightly in place while the form is being used. r)The sidesand partitions are preferably made of wood covered witl'i sheet instal,so that they are very strong and rigid, and will not warp from use ormoisture. Experience is not necessary for anyone to be able to use theform, and the posts may be made with a minimum expenditure et' time andlabor.

lin buildingl a fence with concrete posts made by means of this mold,the longer post 34 with its anchor base 3S will genen ally be used` atthe corners and for gate posts. rEle extended portion is approximatelyeighteen inc long, so that it provides a very' iirm l ase. Adjacent thispost, the double-brace posts 33 may be used`r and the remainder of thetence constructed with common posts 3l.
